Oil on Spark Plugs

Oil on Spark Plugs
So I changed my spark plugs recently, and found oil on plug #2, 5, and 6.
This means I need a new Valve cover gasket correct? If I do replace my valve cover gasket what else should I replace or inspect while I'm in there?
Also I found this washer in the gulley for plug #5, any idea where it came from or why it was there?
It was just sitting there, and made me think my spark-plug was stripped because I couldn't grip onto it with my ratchet. I was honestly about to give up until I took a picture of it to see if anything looked weird, and woila, there it was. Could it have caused any damage by sitting down there when the car was running?

Thats it in the center, and no it's not still in, I removed it with a magnet and the plug came out fine once I figured out what was blocking me from removing it. Cars back together and driving, I'm mainly just curious about the Valve Cover Gasket job an what else to look at when I go in there.

Dude that "Washer" is your Piston seal. it would be a good idea to replace your gasket, but not before having your engine serviced by a certified toyota/lexus technician. Good Luck

I tried searching for info about the "piston seal" but I really couldn't find anything, could you give me some more guidance as to what this part is, and where it goes? I'm not terribly convinced right now, and I have no intention of taking it to a mechanic. I've never taken it to a mechanic since I've owned it, and no intention of doing that.
If you have more info though I would love to read it, also still looking for more info about what else to do while in there for the valve cover gasket which is most likely the cause of the leak around the 3 spark plugs. So far it doesn't look like there was much more to get down to the valve cover gaskets as all I need to do is remove the Y-piping on the intake manifold to pull the valve covers up. Seems silly to pay a shop $700+ for something I could do in a couple hours on a day off. I don't make that much money in a day at my job, and I'd rather know the job was done right than to wonder what was done and if it was done properly.
Maybe do you mean piston rings? Because the piston rings on this car look nothing like that washer.

I checked your thread out and a few others that came up in a search a few days ago for pictures and got a decent idea of what to do, seems like I was only a few more steps away from them when I was doing the spark plugs, just remove EGR, and get the y-pipe tilted back enough to unbolt the valve covers and pull them up then gaskets are right there correct?
